Hanscom Field, a civilian general-aviation airport adjacent to the Air Force Base, and Massport are the primary operators of the air field and runways. Less than one percent of the air traffic at Hanscom Field is military aircraft.

Hanscom Air Force Base began its existence while the United States was considering its entry into World War II. In May 1941, the Massachusetts Legislature authorized the purchase of a large tract of farmland spanning the borders of the towns of Bedford, Lincoln, Concord and Lexington for a Boston Auxiliary Airport. Funds to build the new airport were contributed by the federal government, which had appropriated $40 million to build 250 new civil airports across the United States that could serve for future national defense.[2]

In February 1943, the airport was renamed Laurence G. Hanscom Field in honor of a Massachusetts-born pilot and aviation enthusiast who had been a reporter for the Worcester Telegram-Gazette. Hanscom had died in February 1941, in an aircraft accident in Saugus, Massachusetts, while he was lobbying vigorously at the State House for the establishment of the airport at Bedford.[2]

Later in the war, the Bedford Army Air Field served as a site for testing new radar sets developed by MIT's Radiation Laboratory. It was this secondary wartime activity at Hanscom that gave rise to the base's postwar role.[2]

Since 1945 Hanscom has emerged as the Air Force's center for the development and acquisition of electronic systems. The base has also played a significant role in the creation of a national high-technology area around Route 128.[2]

World War II established the key military importance of radar. In 1945, when the MIT and Harvard wartime laboratories were dissolved, the Army Air Forces aimed to continue some of their programs in radar, radio and electronic research. It recruited scientists and engineers from the laboratories, and its new Air Force Cambridge Research Laboratories (AFCRL) took over MIT's test site at Hanscom Field.[2]

By 1950, the Air Force was working closely with MIT to develop a new air defense system for the continental United States. Expanding its facilities at Hanscom Field was a step to accomplishing this massive project. After some negotiation, the Commonwealth of Massachusetts agreed in May 1952 to cede land on one side of the airport to the federal government and to give a 25-year renewable lease on the airfield itself.[2]

The first buildings for the new MIT Lincoln Laboratory at Hanscom were completed in 1952, and the Air Force's electronic and geophysics laboratories in Cambridge started to migrate out to its own new facilities in Bedford in 1954. The airfield's runways were reconfigured and expanded in 1953, and new hangars, headquarters and facilities were built. To provide test and evaluation for Lincoln Lab's new "Cape Cod" experimental air defense system, Hanscom's 6520th Test Support Wing logged thousands of hours of flying time.[2]

The Semi-Automatic Ground Environment (SAGE) air defense computer system, completed in the early 1960s, revolutionized air defense and also contributed significantly to advances in air traffic control systems. As the SAGE system matured, the Air Force pursued the development of a number of advanced command, control and communications systems.[2]

In 1961 the Electronic Systems Division (ESD) was established at Hanscom Field in order to consolidate the management of the Air Force's electronic systems under one agency. Since that time, the Electronics Systems Division (re-designated the Electronic Systems Center in 1992) was the host organization on the base.[2]

While Hanscom's role in system acquisition flourished after the 1950s, its operational mission gradually diminished. As of September 1973, all regular military flying operations at Hanscom ceased. The following year the Air Force terminated its lease of the airfield portion of Hanscom Field, which reverted to state control, but retained the right to use the field. The Air Force re-designated its own acreage surrounding the field as the Laurence G. Hanscom Air Force Base. In 1977 the name was shortened to the present Hanscom Air Force Base.[2]

The base saw a second wave of construction during the 1980s. The Electronic Systems Division put up four new systems management engineering facilities (the O'Neill, Brown, Shiely and Bond buildings). For base personnel, there were new service facilities—medical, youth and family support centers—as well as additional housing and a temporary lodging facility.[2]

Since July 1992, Hanscom and the Electronic Systems Center (ESC) have been part of the Air Force Materiel Command. In 1994 the Air Force designated ESC as the Air Force Center of Excellence for Command, Control, Communications, Computers and Intelligence (C4I).[2]

The Standard Systems Group at Gunter Annex, Maxwell AFB, Ala.; the 38th Engineering Installation Wing at Tinker AFB, Okla.; the Materiel Systems Group at Wright-Patterson AFB, Ohio; and lastly the Cryptologic Systems Group at Kelly AFB, Texas; were all attached to ESC between 1993 and 1996 in order to consolidate related functions in AFMC under the Center, and to support its expanded mission. Subsequent reorganizations changed the groupings, but all the above organizations (though renamed) except the 38th EIW remained under Hanscom's reporting chain.[2]

In 2004, ESC was reorganized into a named wing, group and squadron unit, to better reflect the organization of the Air Force as a whole. In 2006, the wings, groups and squadrons were given numbered designations. In 2010, ESC reverted to an organization of program offices and the 38th Engineering Installation Wing (by then a group) was reassigned. New Air Force standards caused the 66th Air Base Wing, because of its size, to be redesignated the 66th Air Base Group.[2]

In June 2011, the Air Force Research Laboratory Sensors Directorate moved from Hanscom to Wright-Patterson AFB, Ohio, and the Space Vehicles Directorate moved to Kirtland Air Force Base, New Mexico, closing more than 60 years of laboratory presence on Hanscom.[2]

The Electronic Systems Center as an organization was realigned in July 2012, and became a part of the newly created Air Force Life Cycle Management Center at Wright-Patterson AFB, Ohio.[2]
